STRAIGHT-WAY VALVKE.

SPECIFICATION forming part of Letters Patent No. 296,046, dated April 1, 1884.

Application filed July 24, 1883. (No model.)

To allwhom it may concern:

Be it known that I, P. B. PAGE, a citizen of theUnited States, residing at Lorain, in

the county of Lorain and State of Ohio, have invented certain new and'useful Improvetion.

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of this invention is to produce a straight-way-valve system of simple, economical construction, and reliable automatic operation. These results are attained by the mechanism illustrated in the drawings herewith filed as part hereof, in which the sameletters of reference denote thesame parts in the dif-l ferent views.

Figure 1 is a side elevation, partly in section. Fig. 2 is an end elevation, partly insec- Fig. 3 is a top view, partly in section. Fig. 4 is a front elevation of one of the valves. Fig. 5 is a top view of one of the parts detached. 1

A A A represent the shell forming the valvechamber, and screw-threaded projections for connecting the same with the pipes or conduits.

A is the top or cap, which is secured to the shell A by screw-bolts a.

B is ascrew-threaded spindle, the thread of.

which fits somewhat loosely in a correspondingly-screw-threaded perforation through the rectangular projection O, forming part of the valve 0.

G is a valve, the motion of which is dependent on the motion of the valve 0.

D is a link having central slot, cl, for

the valves 0 O by its ends or rounded edges J J entering corresponding recesses, d and d, in the sides thereof. The valve 0 is provided with rectangular projections or arms G, made integrally therewith, and which enter and fit loosely in oblong recesses c in the valve 0.

E is a packing-nut, which screws into the stuffing-box E, and, by reason of the pack ing intervening between it and the collar on the spindle, secures the same in position.

F is a lug or step inthe bottom of the valve chamber, with which the valve G comes in contact preparatory to closing the conduits.

at the lower ends of the ribs H willallow the link D to assume a position perpendicular to the sides of the valves 0 O, the link will act as a cam and give the valves lateral motion,

and force them tightly against the valve-seats a When the spindle B is turned in a direction to cause the valves to ascend, the valve 0 will start before the valve 0 begins to move, and will move sufficiently to bring the link D to the inclined position shown in Fig. 1, simultaneously with which the arms or pro j ections G of the valve 0 will engage with the upper ends of the recesses c in the valve 0, and thereby cause it to ascend and open the correspondingconduits. Therectangularprojection G of the valve 0 will engage with the cap A when the conduit-ways are opened, and thus prevent the lower end of the valve 0 from getting above the projection inside the shell, which forms the valve-seat c.

The screw-threaded perforation in the projection of the valve 0, through which the spindle B works, should be large enough to allow the link D, when assuming aposition at right angles to valves; to move the valve 0 against the valve-seat a without straining the spindle B.

Having explained the construction and operation of my improvement, what I claim as new, and desire to secure by Letters Patent, 1s

The valves 0 O G and the link D,all constructed as shown, in combination with the shell A, having inner ribs, H H, lug F, and

spindle B, substantially as specified, and for n the purpose set forth:

In testimony whereof I affix my signature in presence of two witnesses- PETER B. PAGE.
